Slow system, trouble loading pages

My PC is running very slow, and has trouble loading some webpages. For example, Facebook cannot load at all. I suspect some sort of virus, but my AV SW does not detect anything on scans. Occasionally, my AV SW has an error and shuts down. I also have a spyware SW, but that does not detect anything either.

after some difficulty, I finally managed to complete the 8 steps.
For some reason, I couldn't update the Java version, but I finally was able to do this. My Antivirus (norton internet security) still crashes.

the logs are attached

Thanks for any help

OK. You will have to excuse my ignorance & inability to complete the task.

I got started in safe mode, opened the command prompt and am at the root c:\ directory.
But I can't paste the code that you have listed here. When I try to paste (Ctrl V), all that gets written is ^V

Do the below and reboot and report back the status of your computer, is all well?

Update then run SAS
Click Preferences-Repairs
Then counting down from top do the following entries

Numbers 6, 8, 11, 12, 13, 15,18, 19, 20, 21, 22, 24, 25, 26 and 27!

Reboot the test for Google redirecting! let me know!

The Norton removal tool was written by Symantec to remove corrupted installations or failed uninstalls only. They advise to always try the normal uninstall first. Then it was discovered that it helped to get even more of the crap Norton leaves if run after a successful uninstall. And it still leaves hundreds of files and registry entries!

it's really odd. all other sites load much faster than previously (thank to all your assistance). Even graphic heavy espn.com loads up almost instantly. But facebook always hangs. I've been trying to research it some, and it appears many folks have had the problem. People have tried disabling AV, changing browsers, different OS, etc. But I have not stumbled across anyone who has posted a solution. very strange.

But, while in Safe Mode, I was able to open Facebook, but is crashed IE right after the page loaded. I got the following message:
Program Error
IExplorer.exe generated errors and will be closed by Windows.
An error log has been created

Then IE shut down shortly after.

This happend twice.

I rebooted to normal mode, then added facebook to the list of trusted sites.
It opened and appears to work normal for now.

Approve all if prompted by Firewall. Approve Widows Defender or other guards or security programs while OTCleanIt attempting access to the Internet to allow all.

If prompted to Reboot click, Yes.
OTCleanit will delete itself when finished, If not delete it by yourself.

Run CCleaner again twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

Then Start-Programs-Accessories-System Tools-Disk Cleanup
Click OK to accept C:
Select all Boxes
Then click More Options
Here click System Restore and OK to "Are you sure" and the OK to Run.

As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

It clears what is known as Shadow copies which are used by specialized back up programs.

This is if you have the Volume Shadow Copy running which is the default.
-------------------------------------------------------------------------------------

Every two weeks or so, run MBAM and SAS until clean.

They take a while, so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be scheduled not to interfere with computer time.

If they find something they can not clean, then get back to us.

Additionally run CCleaner. ATF-Cleaner and KCleaner.

I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

It was designed to be used with and to co-exist with other Virus scanners.

Additionally it uses a totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity.

It's like looking at it with 2 sets of eyes and from a different angle.

It works like some Firewalls do to learn what is good/bad.

After install it will ask you about everything that could be a security issue. For example the first time you run IE or FireFox it will prompt you. You would answer to approve and remember the setting. From then on no more prompts about IE or FireFox unless the exe changes like in an update.

As it queries you about the prompt to help you determine to approve or not you can google it with one click.
